Annular disk for reduction of anastomotic tension and methods of using the same
First Claim
1. An apparatus for forming an anastomosis between adjacent tissue sections, the apparatus comprising:
- a) an anastomosis device including an anvil assembly having a shaft which is selectively attachable to a tubular body portion, wherein the tubular body portion includes at least one annular row of staples operatively disposed therein; and
b) a disk having an outer terminal portion and a substantially centrally located aperture, the disk including an adhesive material at the outer terminal portion, wherein the outer terminal portion of the disk extends radially outward beyond the outer-most row of the at least one annular row of staples to adhesively attach the tissue sections together radially outward of the at least one annular row of staples.

Abstract
An apparatus for forming an anastomosis between adjacent tissue sections is provided. The apparatus includes an anastomosis device including an anvil assembly having a shaft which is selectively attachable to a tubular body portion, wherein the tubular body portion includes at least one annular row of staples operatively disposed therein. The apparatus further includes a disk having an outer terminal portion and a substantially centrally located aperture. The disk includes an adhesive material at the outer terminal portion. Wherein the outer terminal portion of the disk extends radially outward beyond the outer-most row of the at least one annular row of staples to adhesively attach the tissue sections together radially outward of the at least one annular row of staples.

7. A method of performing an anastomotic procedure on adjacent tissue sections, the method comprising the steps of:
-
a) providing a surgical stapling device including an anvil assembly and a body portion, the anvil assembly including an anvil member supported on an anvil shaft and the body portion carrying a plurality of surgical staples arranged in an annular row and a knife;
b) providing an adhesive disk having an outer terminal portion and a substantially centrally located aperture, wherein the outer terminal portion of adhesive disk extends radially outward beyond an outer-most row of the at least one annular row of staples;
c) inserting the anvil assembly into a first tissue section;
d) inserting the body portion into a second tissue section;
e) disposing the adhesive disk between the first tissue section and the second tissue section;
f) approximating the anvil assembly and body portion with one another so that an end portion of the first tissue section, an end portion of the second tissue section, and the adhesive disk are disposed between the anvil member and the body portion, wherein the adhesive disk is disposed between the first tissue section and the second tissue section and the outer terminal portion thereof extends radially outward beyond the outer-most row of the at least one annular row of staples, wherein the adhesive disk adheres the end portions of the first and second tissue sections to one another;
g) deploying the staples from the body portion; and
h) cutting the first tissue section, the second tissue section, and the adhesive disk with the knife. - View Dependent Claims (8, 9, 10, 11)

12. A method of joining adjacent tissue sections, the method comprising the steps of:
-
a) providing a surgical stapling device including an anvil assembly having an anvil shaft, and a body portion carrying a plurality of surgical staples arranged in an annular row and a knife;
b) providing an adhesive disk having an outer terminal portion which extends radially outward beyond an outer-most row of the at least one annular row of staples;
c) inserting the anvil assembly into a first tissue section;
d) inserting the body portion into a second tissue section;
e) disposing the adhesive disk between the first tissue section and the second tissue section;
f) approximating the anvil assembly and body portion with one another so that the first tissue section, the second tissue section and the adhesive disk are disposed between the anvil member and the body portion, wherein the adhesive disk is interposed between the first tissue section and the second tissue section, and wherein the outer terminal portion of the adhesive disk extends radially outward beyond the outer-most row of the at least one annular row of staples;
g) deploying the staples from the body portion; and
h) cutting the first tissue section, the second tissue section, and the adhesive disk with the knife. - View Dependent Claims (13, 14, 15, 16, 17)
